IRS says Americans making fewer mistakes on tax returns

WASHINGTON, D.C. (WITI) -- The IRS says Americans are making fewer mistakes on their tax returns.

The agency found 2.7 million errors made by two-million taxpayers on their 2011 returns.

That's less than half the mistakes found on 2010 returns.

Tax software programs, such as H&R Block and Turbo Tax, may be the reason for the decline.

Taxpayers who use them are less likely to make mistakes, according to a Georgetown University accounting professor.
